Owlet Dream Sock monitors your baby’s oxygen and heart rate via a wearable sock. Nanit Pro monitors breathing motion and sleep patterns via an overhead camera. They track completely different things.
- Best for oxygen and heart rate tracking: The Owlet Dream Sock (~$299) uses a wearable sensor to monitor vitals in real time
- Best for video quality and sleep analytics: The Nanit Pro (~$299) utilizes an overhead camera and computer vision to track sleep patterns
- Want both functions in one brand → Owlet Dream Duo 2 (~$399–449)
- Both together is the most complete setup — and what many parents end up doing

The Core Difference Nobody Explains
Most comparison articles treat Owlet and Nanit like two versions of the same product. They’re not.
The Owlet Dream Sock is a wearable health monitor. It clips onto your baby’s foot and measures pulse rate and blood oxygen (SpO2) in real time — the same metrics tracked in a NICU. If readings drop outside safe ranges, the base station lights up and sounds an alert.
The Nanit Pro is an overhead camera with sleep intelligence. It mounts above the crib and uses computer vision to track your baby’s breathing motion through a pattern printed on special Nanit sleepwear. It does not measure oxygen or heart rate — but it gives you HD video, temperature and humidity monitoring, and detailed sleep analytics you can actually show your pediatrician.

Owlet Lineup: All Models
1. Owlet Dream Sock — The Health Monitor
The Dream Sock is the product that built Owlet’s reputation. A small sensor clips onto your baby’s foot and reads pulse rate and blood oxygen via pulse oximetry — the same technology used in hospital monitors — sending live data to the Owlet base station and app.
How it works: Slide the sock onto your baby’s foot before sleep. The base station glows green when readings are normal. If oxygen or heart rate drops outside preset thresholds, it lights up red and sounds an alert through the app and base station.
Best for: Parents of newborns, preemies, or any baby where oxygen monitoring provides meaningful reassurance.
2. Owlet Cam 2 — Standalone Camera
The Owlet Cam 2 is a 1080p HD camera with night vision, two-way audio, temperature monitoring, and cry detection. No sock, no health data — just a reliable camera at a much lower price point than the flagship Dream Sock.
Best for: Parents who already own the Dream Sock and want to add video without switching brands or apps.
3. Owlet Dream Duo 2 — Sock + Camera Bundle
The Dream Duo 2 bundles the Dream Sock and Owlet Cam 2 into a single package with one app. It’s the closest Owlet equivalent to the Nanit Pro Complete — health monitoring and video in one brand ecosystem.
Best for: Parents who want oxygen, heart rate, and video in one single-brand setup with one app.
Nanit Lineup: All Models
1. Nanit Pro — The Sleep Intelligence Camera
The Nanit Pro is a 1080p overhead camera that mounts above the crib and pairs with Nanit’s Breathing Wear to track your baby’s breathing motion without any wearable sensors. It’s genuinely the best sleep analytics system for parents who want real data on sleep patterns, wake times, and overnight trends.
How it works: The camera reads a geometric pattern printed on the Nanit Breathing Band or Breathing Wear sleeping bag. The camera tracks that pattern to detect breathing motion and sends a notification if motion isn’t detected for a set period.
Best for: Parents past the early newborn anxiety phase who are focused on understanding sleep, or anyone who wants the best video and analytics available.
2. Nanit Pro Complete — Camera + Floor Stand Bundle
Same camera and analytics as the Nanit Pro, with a floor-standing mount included — no wall installation required. If you rent, move frequently, or just don’t want to drill above the crib, this is the version to get.
Best for: Renters, families who move the monitor between rooms, or anyone who wants the Nanit Pro without a wall mount.
Subscription Costs: The Hidden Expense
Both brands gate meaningful features behind a subscription — and most comparison articles underplay this.
| Owlet+ | Nanit Insights | |
|---|---|---|
| Free tier | Live readings + basic alerts | Live video + basic motion alerts |
| What’s paywalled | Historical data, sleep insights, expanded notifications | Sleep analytics, breathing history, multi-camera, full dashboard |
| Monthly cost | ~$9.99–$24.99/month | ~$6.49–$19.99/month |
| Annual cost (mid tier) | ~$120–$200/year | ~$78–$240/year |
Can you use the Owlet or Nanit without a subscription? Yes. Both the Nanit Pro and Owlet Dream Sock allow you to view live video streams and receive real-time safety alerts for free. However, a paid subscription is required if you want to save overnight sleep data or view historical health trends.
The Case for Using Both Owlet and Nanit
Many parents end up with both — and it makes more sense than it sounds.
The Owlet Dream Sock handles what the Nanit can’t: real vital signs. The Nanit handles what the Owlet can’t: best-in-class video and sleep analytics. Used together, you get oxygen monitoring for the newborn stage when that data matters most, and a full sleep intelligence system for the months when sleep patterns and training become the priority.
The combined cost (~$598 in hardware plus subscriptions for both) is real. But parents who go this route consistently say it covers every monitoring anxiety in one setup. If your budget allows it and peace of mind has high value for your family, it’s a defensible call.
Owlet vs Nanit: Frequently Asked Questions
Does the Nanit track oxygen levels?
No. The Nanit Pro tracks breathing motion through a camera and patterned sleepwear — it does not measure blood oxygen (SpO2) or heart rate. If oxygen monitoring is your priority, you need the Owlet Dream Sock.
Is the Owlet Dream Sock FDA-cleared?
Yes. The Dream Sock received FDA 510(k) clearance as a prescription-free consumer pulse oximeter, using the same pulse oximetry technology as hospital monitors.
What age does the Dream Sock work until?
The Dream Sock works for babies between 5 and 30 lbs — roughly 1 to 18 months depending on your baby’s size. Most babies outgrow it somewhere between 12 and 18 months.
Can I use the Dream Sock without buying a camera?
Yes. The Dream Sock works completely independently as a standalone health monitor — no Owlet camera required.
Does the Nanit work without the Breathing Band?
The Nanit Pro functions as a video monitor without Breathing Wear, but breathing motion tracking — the feature that most justifies its price — requires Nanit’s Breathing Band or Breathing Wear. Without it, you have a good HD camera but not the full Nanit experience.
Nanit vs Owlet for twins?
Nanit supports multiple cameras in the same app (with subscription) — one camera per crib. For the Owlet, you’d need two Dream Socks, one per baby. Both work in the same app; factor the multi-camera subscription cost into your Nanit decision.
Is either monitor worth it for a healthy, full-term baby?
Both are premium products for parents who want more data than a standard video monitor provides. For a healthy full-term baby with no medical history and no parental anxiety around vitals, a standard video monitor covers most real-world needs. The Owlet and Nanit are worth it when the additional data genuinely changes how you sleep or parent. That’s a personal call, not a medical one.
Pick one based on what’s keeping you up at night — literally.
If it’s oxygen and heart rate in the newborn stage, get the Owlet Dream Sock. If it’s sleep tracking and video quality from three months onward, get the Nanit Pro. If you want both functions in one brand, the Dream Duo 2 bundle covers it, though the camera side doesn’t match Nanit’s analytics. And if budget isn’t the constraint, using both is genuinely the most complete baby monitoring setup available.
